I just got my first 2 BR pullets - 16-18 wks old. They are "free ranging" in my 40' X 90' greenhouse. I have a box for them, but they don't use it. One of them roosts on a greenhouse table turned on its side ( so she's 4 feet up!!) The other goes somewhere where I can't find her at night. I'll try to watch her tomorrow at dusk. I have a light on at night over the box, feed, water and roost I made that they don't use, but neither "sleeps" in the light. Is it doing any good? Should I confine them at night? I got them on 11/12/09. Any advise would be helpful. These are my first two babies!!
